1. OVERVIEW OF MIGRATION FROM Q17nDCPU(-S1) TO Q17nDSCPU
1.1 Benefits of Migration
Migrating from the existing system using Q173DCPU(-S1)/Q172DCPU(-S1) Motion controllers to
a new system using iQ Platform Motion controllers Q173DSCPU/Q172DSCPU (hereinafter
called Q17nDSCPU), which support the programs on the Q173DCPU(-S1)/Q172DCPU(-S1), is
recommended. We also recommend migrating servo amplifiers to the MR-J4 series at the same
time.
Migrating not only allows the system to run for longer periods, but also has the following
advantages.
(1) High-speed operation and high functionality of the Motion controller
The Motion controller Q17nDSCPU achieves the operation cycle of 0.22 ms/4 axes, enabling
a dramatically fast operation.
The controller also achieves further advanced motion control with a wide variety of motion
control functions.
→
Increased productivity from higher speeds and functionality of the Motion controller
(2) High-speed communication by SSCNETIII/H
Speeding up and improving noise tolerance of servo system network communications are
achieved by optical communication. A long distance cable of 100 m can be also used.
→
Increased speeds over the entire facility
(3) Servo amplifier MR-J4 and servo motor
The servo amplifier MR-J4 series achieves high performance operation with a variety of
functions including one-touch tuning, a 22-bit high resolution encoder (4194304 pulse/rev),
and 2.5 kHz speed frequency response. The product line includes multi-axis servo amplifiers
that contribute to energy saving, space saving, and reduced wiring of a machine. The MR-J4
series compatible rotary servo motor, HG series enables to output high torque at high speed.
Linear servo motors and direct drive motors are also available. Select the motor type
according to your application from our extensive product lines.
→
Increase of applications, improved performance, energy saving, downsizing, and reduced
wiring of drive systems
(4) Lower maintenance cost
After 5 years of usage, the products will need maintenance, such as replacement of the whole
circuit board due to the life of components including electrolytic capacitors and memories.
To use the system the longest possible, an early migration to the latest model is
recommended in terms of performance and quality.

Increased equipment longevity
